Metal may actually be copper, but I'm not sure, so I'm saying it has a copper-like finish. Made in linked sections that are set with oval turquoise stones. Fastens with a toggle through a loop. The individual sections measure 5/8" wide by a little less than an inch long. The toggle isn't a precise closure, so the total length, as worn, is 7"-7.5". Condition is great with some variation in the color of the finish.
